Caviar Wars
The Shah of Iran granted the concession to a Russian business to fish in Iran's territorial waters i.e. the southern shores of the Caspian Sea. [Saffron, Inga; "Caviar: The Strange History and Uncertain Future of the World's Most Coveted Delicacy"; 2002; page 43]
Russian Revolution
The Shah of Iran cancels the concession to a Russian business after non-payments, and is granted to another Russian business, which subsequently also fails to make payments to Iran. The concession is cancelled and the Shah grants no further ones, opting instead for Iran to make full use of her fishing grounds in her territorial waters.

Our Beginning's
February 1953, Iran terminates a fishing concession with the Soviet Union, thereby denying access to sturgeon in the southern Caspian Sea.

The Shah and Caviar
During the reign of Shah Pahlavi of Iran, the nation had secured sovereign right to the production of sturgeon in the southern part of the Caspian Sea, which also permitted consumption of caviar by Iranians as well. [Shardina, Ekaterina ; The Great Caspian Caviar Game; 2007; Security Index: A Russian Journal on International Security Volume 13, 2007 - Issue 1, pages 55-78; https://doi.org/10.1080/19934270.2007.9756489] Shah Reza Pahlavi was famously allergic to caviar [Cooper, A. S. (2012). The Oil Kings: How the U.S., Iran, and Saudi Arabia Changed the Balance of Power in the Middle East. United Kingdom: Simon & Schuster.; Page 381]
Islamic Revolution
The Iranian authorities temporarily bans consumption of sturgeon and caviar in Iran until it was determined that it is permissible in Shiite Islam. [https://online.ucpress.edu/gastronomica/article-abstract/7/2/17/47334/How-Caviar-Turned-Out-to-Be-Halal] US President Ronald Reagan bans import of sturgeon products into the US. As the US consumed 80% of caviar (Iranian or other), this had a signficant effect on caviar industry in Iran. [https://home.treasury.gov/system/files/126/iran.pdf]
USA Removes Caviar Sanctions
USA removes ban on importing food products from Iran, permitting direct export of caviar from Iran to the US. [https://www.treasury.gov/press-center/press-releases/Pages/ls760.aspx]
